KOHLER (MAHLE) PISTON ASSEMBLIES

In 2006 Kohler was having some problems with incidents of smoking on start-up, primarily with Command vertical twin engines, and through research found that oil was settling in the combustion chamber above the piston. This was caused by the oil slots inside the piston being too large,now the pistons have been redesigned to significantly reduce the amount of oil that can collect and get past the ring grooves into the combustion chamber when the engine is shut down.

But that in the new piston poses a new problem. In most cases the Mahle piston cannot be used in place of the old piston without changing to the new style connecting rod as well, with some of these new rods costing around $70. Also, if the rings ever have to be replaced on these Mahle pistons you have to use the new style rings as well.

All of the pistons that we carry in the aftermarket here at TEW are the old style pistons and can be used with the old style rods, and rings.  But, we also carry a full line of Kohler piston assymblies so it is crucial to be certain of your engines needs.

I have posted the Kohler Piston Parts Bulletin 246 so that you will be able to identify what pistons that you have and we will be able to find you the right parts for your machinery.

Honda Variation Codes

If you have ever tried to order parts for your Honda engine, you have probably been asked “Do you have your variation code?”.

It seems simple enough, if you have your model number you should be able to find anything that you need for this, but it’s just not that easy. Were going to take a look at Honda variation codes and what they mean. To start we’ll  just take a look a the GX160, this is a simple 5.5 HP engine but most people do not know that there are actually 479 variations of this engine. Now most of the differences are due to different crankshafts that are used for numerous applications, but there are also other differences in each one of these engines. Some of them have different air cleaners and others may have different features such as electric start or oil alerts. So take some time to check out the chart below for basic information about Honda model and variation numbers.
